Following a successful pilot project, the northern German federal state of Schleswig-Holstein has decided to move from Microsoft Windows and Microsoft Office to Linux and LibreOffice (and other free and open source software) on the 30,000 PCs used in the local government. As reported on the homepage...
This is great news, but it is always worth remembering the ebb and flow of these things. It happens because an individual cared. Eventually, that individual won't be in the decision-making process, and the office will likely come back. At least it usually goes thst way.
This part of Germany has supported open source software for a long time now. So this didn't come unexpected or without a decade long preparation.
The most important part is not the product here. Unfortunately, the people who work with the software decide. It's also a huge effort to educate all the people to use LibreOffice.
The nice thing is that MS Office moves entirely to the cloud and SaaS. Schleswig Holstein are the only one who will be prepared for the worst soon.
